Plants produce food through a process known as photosynthesis. Photosynthesis is a process used by green plants to create their own food.

Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll, which is typically found in leaves of green plants, is present in all such plants. Plants take up both carbon dioxide from the air and water from the soil. Autotrophic plants are those that can manufacture their own sustenance.

The process of photosynthesis occurs in the chloroplast, a part of plant cells. The photosynthetic pigment chlorophyll is found in chloroplasts, which are found in cells.

There are various reasons to why it is important to study genetics.

=====================================================

"Why do you think it is important to study genetics?"

=====================================================

Genomics (aka. study of genetics)- is a field of study that helps geneticists describe every length of a person's genes (aka. the genome). By studying genetics, one can learn more about your current health and be made more aware of your family's history of good and bad genetics that either you carry, your family carries, or one that you may carry onto your offspring. The study can help answer questions such as:

For the first question, everyone has genes that are built in their DNA through their family; some genes may be passed or you could pass them onto your children. Some genes in this case can include your personality, interests, or talents that are passed to you through your genetics in your family.

For the second question, everyone's family usually shares vary similar genetics, and most often if the genes are dominant, it can result in many of your family members looking alike. For instance, if you have a strong history of brown hair and brown eyes in your family, however have very few blue eyed genes, most likely a majority of your family would be expressing the brown hair, brown eyed genes since it is a dominant inherited gene. Blue eyes (aka. blue eye allele gene) is recessive, so the less blue eyed genes you have in your family, the more likely the brown eye gene will dominant the blue eyed gene.

And as for the last question, some diseases can run in families due to them either being dominant or recessive. For instance, both diabetes and cancer are considered autosomal dominant link mutations; in other words, the two are conditions that can be passed onto children even if only a single parent carries the gene or has the gene. Knowing this, it would always be wise to study further on your family's health history to be aware of possible future health conditions to either you or your other family members.

__________________________________________________

In summary to this, it is and always will be important and wise to study further in genetics for not only your curiosity, but to also inform you about your history DNA wise and health wise. You can also have a better chance of stopping genetic diseases in early stages of development before they override possibilities to a cure.

In a sample of DNA, nucleotide thymine will make up 12% of the total.

According to Chargaff, nucleotide subunits make up the DNA. The double-stranded DNA molecule is created by these nucleotides forming hydrogen bonds with one another.

The following nucleotides can be found in the DNA molecule:

Guanine (G) pairs with Cytosine, while Adenine (A) pairs with Thymine (T) (C).

According to Chargaff's rule, the ratio of adenine to thymine in a DNA molecule is equal. Same holds true for the cytosine and guanine. The entire number of nucleotides, however, is 1, or 100%.

A + T + G + C = 100%.

If the DNA sample's cytosine content is 38%, then the DNA sample's guanine content must be 38% as well.

G (38) + C (38) = 76%

100% - 78% = 24%

Thus, the combined amount of adenine and thymine is 24%. Each nucleotide will make up 24% 2 = 12% of the total, thus that A = T = 12%.

The prediction that can be made about the population of birds when DDT is present in the ecosystem is option  C. The population of birds will decrease when there is a higher concentration of DDT because thin eggshells will break more easily than normal eggshells during incubation.

DDT is a pesticide that was widely used in the United States from 1943 to the 1970s. One of the environmental issues caused by DDT is its effect on birds in the ecosystems where the pesticide was applied. DDT causes thinning of the bird's eggshells, which can lead to decreased hatching success and population declines of bird species.

DDT works by disrupting the calcium metabolism in birds, which causes a decrease in the amount of calcium available for the formation of eggshells.

Therefore, The shells of eggs laid by birds exposed to DDT are thinner and weaker than normal, making them more likely to break during the incubation period. This reduction in the number of birds hatching and surviving, ultimately leads to a decrease in the population of birds in the ecosystem.

One of life's fundamental properties is the ability to reproduce itself. Now, researchers have created the first ribonucleic acid molecules, a single-stranded relative of deoxyribose nucleic acid, which can reproduce nearly any other RNA.

In 1993, scientists created a ribozyme dubbed RNAP, also referred to as an all-RNA form of RNAP. On a separate template strand, it joined two short RNA strands. The problem with all of these RNAP ribozymes is that they are only able to duplicate specific nucleotide base sequences, which are the building blocks of RNA and DNA, and such sequences have no real biological significance in living cells. Joyce and his colleague started by synthesizing a vast library of DNA strands to encode the original RNAP ribozyme. They changed the DNA sequence at random to guarantee that every final RNAP was distinct. These RNAPs were part of a vial containing a collection of brief RNA fragments that the researchers hoped to join together on another template strand. If the new RNA was successfully created, the new strand would bind to a specific molecular target in its vial as a sign that RNAP ribozyme was successful. Due to the fact that each RNAP ribozyme was created to remain affixed to its particular, generated RNA strand, the researchers were able to identify any accomplishments. Each captured RNAP ribozyme was then used as the starting point for a fresh round of evolution. This 24-round test-tube evolution produced an RNAP ribozyme known as 24-3 polymerase, which is currently the product. Throughout this process, the requirements for an efficient RNAP ribozyme were gradually enhanced. The ability of the 24-3 polymerase to duplicate previously duplicated RNAs allows it to amplify the presence of certain RNAs 10,000-fold. As a result, the first RNA version of the polymerase chain reaction, a technique widely used to copy DNA, was created.

It moves a distance of in the y-direction of 0.005 m.

The electron is moving at a speed of 2 m in the x direction vₙ = 1.60 x10⁸

Time of flight is t = d/ v where d is distance and v is velocity

t=2m/ 1.60×10⁸ms⁻¹ =1.25×10⁻⁸s
